Bought a last minute eticket for Download festival from Viagogo - I originally wasn't going to go due to cost but when i saw this ticket at half price of the face value i could afford that. I drove 2 hours to the festival and was refused entry as the eticket had already been used. I rang up Viagogo customer service and they said they were unable to help me. Tickets were still on sale at the box office at face value but they refused to get me a replacement my ticket. Download festival staff on the gate said they had already turned away lot of other people for having invalid tickets they bought from Viagogo. This is apparently was a common problem with Viagogo customers. Viagogo's offer of a refund within a week was not much help when you are standing at the gates of a festival foced to shell out another £220 for a replacement ticket you hadn't budgeted for, which even if i eventually get the refund will be £100 more expensive I originally paid them for the ticket. Completely inadequate customer protection and waste of time 'guarentee' - if you buy a ticket there is no way of knowing if it will be valid until you get there and if it isn't you are screwed and then have to chase Viagogo for your money back. You are relying completely on the individual seller using Viagogo being trustworthy and not selling the eticket more than once or using it themself as Viagogo has no way to stop this happening despite you paying a ridiculously high fee for them to do nothing (in this instance the Viagogo transaction fee was about £30). AVOID!
